Since I can't seem to find a reasonably priced 68060-based system out  
there, I am looking at the CPU upgrade possibilities for 68k Macs. I  
have been reading FAQs all over the place about upgrading Mac CPUs. I  
have read that you can easily swap a 68LC040 out and put a 68040 in  
its place. I have not found a clear answer on one thing though. Can I  
put a faster 68040 chip in place of a slower 68LC040 chip? I just  
purchased an LC 575 motherboard for my Color Classic (which now has a  
Color Classic II board in it) and I want to replace its processor  
with a full 68040. It now has a 33 MHz 68LC040 and I want to put in a  
40 MHz 68040. Would that work? I am thinking it will not but I am  
hoping it will. If that would work than I assume I could upgrade my  
Quadra 650s to 40 MHz 68040 chips as well.
